Rachel the Robot lives in the world on the next slide. We want Rachel to double the number of beepers on a corner in the world. Provide the algorithm needed to double the pile of beepers. You can assume the following:

There is a finite number of beepers on the corner directly in front of Rachel

Rachel has an infinite number of beepers in her bag

Rachel understands the following commands

move() takes one step forward

turn() turns left 90 degrees

pickUpBeeper() picks up 1 beeper from the floor and puts it in the bag

putBeeper() puts one beeper on the floor from the bag

repeat X times / End statements between the X and the End will be repeated X times

while ? / End (statements between the ? Condition and the End will repeat as long as the ? Condition returns true.

Rachel knows how to do the following tests

beepersPresent() returns true if there is at least 1 beeper on the spot Rachel is standing

For example,we started with 5 beepers in the space next to rachel and ended with 10 beepers in the space next to rachel
